This application is filed claiming priority from Provisional Application No. 60/300,028 filed Jun. 21, 2001.

FIELD OF THE INVENTION

This invention relates to encapsulated formulations of cholesterol ester transfer protein (CETP) inhibitors for use in mammals, especially humans, which for mutations provide increased concentrations of CETP inhibitors for absorption, hence higher bioavailability.

BACKGROUND OF THE INVENTION

CETP inhibitors, as a class, are characterized by high binding activity. Such CETP inhibitors are generally hydrophobic, however, with the consequence that they have extremely low aqueous solubility and have low oral bioavailability. Such compounds have generally proven to be difficult to formulate for oral administration such that high bioavailabilities are achieved.

Atherosclerosis and its associated coronary artery disease (CAD) is the leading cause of death in the industrialized world. Despite attempts to modify secondary risk factors (smoking, obesity, lack of exercise) and treatment of dyslipidemia with dietary modification and drug therapy, coronary heart disease (CHD) remains the most common cause of death in the U.S., where cardiovascular disease accounts for 44% of all deaths, with 53% of these associated with atherosclerotic coronary heart disease.

Risk for development of this condition has been shown to be strongly correlated with certain plasma lipid levels. While elevated LDL-cholesterol may be the most recognized form of dyslipidemia, it is by no means the only significant lipid-associated contributor to CHD. Low HDL-cholesterol is also a known risk factor for CHD (Gordon, D. J., et al.,: “High-density Lipoprotein Cholesterol and Cardiovascular Disease”, Circulation, (1989), 79: 8-15).

High LDL-cholesterol and triglyceride levels are positively correlated, while high levels of HDL-cholesterol are negatively correlated, with the risk for developing cardiovascular diseases. Thus, dyslipidemia is not a unitary risk profile for CHD but may be comprised of one or more lipid aberrations.

Among the many factors controlling plasma levels of these disease dependent principles, cholesteryl ester transfer protein (CETP) activity affects all three. The role of this 70,000 dalton plasma glycoprotein found in a number of animal species, including humans, is to transfer cholesteryl ester and triglyceride between lipoprotein particles, including high density lipoproteins (HDL), low density lipoproteins (LDL), very low density lipoproteins (VLDL), and chylomicrons. The net result of CETP activity is a lowering of HDL cholesterol and an increase in LDL cholesterol. This effect on lipoprotein profile is believed to be pro-atherogenic, especially in subjects whose lipid profile constitutes an increased risk for CHD.

No wholly satisfactory HDL-elevating therapies exist. Niacin can significantly increase HDL, but has serious toleration issues that reduce compliance. Fibrates and the HMG CoA reductase inhibitors raise HDL-cholesterol only modestly (˜10-12%). As a result, there is a significant unmet medical need for a well-tolerated agent that can significantly elevate plasma HDL levels, thereby reversing or slowing the progression of atherosclerosis.

CETP inhibitors have been developed that inhibit CETP activity, and thus, if present in the blood, should result in higher HDL cholesterol levels and lower LDL cholesterol levels. To be effective, such CETP inhibitors must be absorbed into the blood. Oral dosing of CETP inhibitors is preferred because to be effective such CETP inhibitors must be taken on a regular basis, such as daily. Accordingly, it is preferred that patients be able to take CETP inhibitors by oral dosing rather than by injection.

However, it has proven to be difficult to formulate CETP inhibitors for oral administration such that therapeutic blood levels are achieved. CETP inhibitors, in general, possess a number of characteristics that render them poorly bioavailable when dosed orally in a conventional manner. CETP inhibitors tend to be quite hydrophobic and extremely water insoluble, with solubility in aqueous solution of usually less than about 10 μg/ml and typically less than 1 μg/ml. Often the aqueous solubility of CETP inhibitors is less than 0.1 μg/ml. Indeed, the solubility of some CETP inhibitors is so low that it is in fact difficult to measure. Accordingly, when CETP inhibitors are dosed orally, concentrations of CETP inhibitor in the aqueous environment of the gastrointestinal tract tend to be extremely low, resulting in poor absorption from the GI tract to blood. The hydrophobicity of CETP inhibitors not only leads to low equilibrium aqueous solubility but also tends to make the drugs poorly wetting and slow to dissolve, further reducing their tendency to dissolve and be absorbed from the gastrointestinal tract. This combination of characteristics has resulted in the bioavailability for orally dosed conventional crystalline or amorphous forms of CETP inhibitors generally to be quite low, often having absolute bioavailabilities of less than 1%.

Various attempts have been made to improve the aqueous concentration of CETP inhibitors, but generally have met with limited success. Conventional methods of formulation do not provide sufficient solubilities and thus poor oral bioavailabilities have been obtained. Pre-dissolving CETP inhibitors in hydrophilic solvents such as acetone or PEG followed by delivery as a solution have failed due to inadequate solubility in the solvent or precipitation upon dilution into the aqueous medium. Suspensions of crystalline drug do not provide sufficient concentrations of drug in solution due to very low aqueous solubilities and therefore yield inadequate blood levels.

One approach that has been disclosed to formulate CETP inhibitors is the formation of CETP solutions in lipids. Solutions in medium chain triglycerides have been of value either as oral solutions or encapsulated in softgels. However, the solubility (65 mg/mL or less) for some of the most potent and useful CETP inhibitors known to the inventors has limited the dose to 30 mg in a reasonable sized softgel. The efficacious dose is expected to be several multiples of this and therefore may require administration of more than 2 softgels per day.

It has also been found that it is necessary to administer triglyceride solutions with food in order to achieve efficacious blood levels of CETP inhibitors. Food effects of 20-30× have been observed in man for some CETP inhibitors, with considerable variability between patients. The food effect is the ratio of plasma AUC values measured for administration of drug with a meal vs. administration in the fasted state. In addition, there is minimal CETP inhibition in the absence of food due to low fasted plasma exposure. As a result, labeling would need to indicate administration with food. This strong dependence of exposure on food could compromise the effectiveness of this medication in the treatment of atherosclerosis if there is a lack of compliance with labeling instructions.

Therefore, there remains a need to develop oral formulations of CETP inhibitors that would reduce the food effect substantially, primarily by improving fasted exposure, thereby minimizing patient-to-patient variability in clinical outcome. An increase in the dose per capsule would also be a desirable improvement.

Lack of mixing between oil formulations and the aqueous environment of the GI tract is known to lead to variable gastric emptying and thus variable absorption. A frequent means of increasing fasted bioavailability of hydrophobic drugs is to use a surfactant or combination of surfactants to produce an emulsion, which, if of sufficiently small particle size can lead to enhanced absorption of the drug. Lipid solutions containing surfactants that spontaneously form emulsions when mixed with an aqueous medium are referred to in the literature as self-emulsifying drug delivery systems (SEDDS) (S. Charman, et. al., Pharm Res., vol. 9, 87 (1992)). They are isotropic mixtures of oil, typically medium chain triglycerides, and non-ionic emulsifier that yield fine emulsions when gently mixed with aqueous fluid, such as in the stomach and intestine, and have the appropriate polarity for fast drug release (C. W. Pouton, Adv. Drug Deliv. Rev, vol. 25, 47 (1997); P. P. Constantinides, Pharm. Res., vol. 12, 1561 (1995); A. Humberstone and W. Charman, Adv. Drug Del. Rev., vol 25, 103 (1997)). Early SEDDS were defined as forming an emulsion with particle size below 5 microns (S. Charman, et. al., Pharm Res., vol. 9, 87 (1992)) and utilized MIGLYOL® and a single surfactant, Tagat TO, which has an HLB (hydrophilic-lipophilic balance) of 10, to form a emulsion with a droplet size of 3 microns. Tagat is not available for human use as are other excipients with the appropriate properties.

Much of the effort in both the open and patent literature has been invested in formulations of cyclosporin. A formulation of cyclosporin that was found to increase bioavailability by in situ generation of an emulsion utilized long chain triglyceride, a polyglycolyzed glyceride, and ethanol and was marketed as Sandimmune® (Cavanak (Sandoz)). See U.S. Pat. No. 4,388,307 (1983). This had the disadvantage of considerable variability in oral bioavailability and PK profile. Subsequently, a self-microemulsifying system was developed (Meinzer, (Sandoz) WO 93/20833; Ritschel, Clin. Transplant., vol. 10, 364 (1996)) using polyethoxylated hydrogenated castor oil (Cremophor® RH40), corn oil mono-, di- and triglycerides, propylene glycol and ethanol. This softgel formulation, marketed as Neoral®, reduced variability in exposure and also reduced the moderate food effect (Mueller, Pharm . Res. vol 11, 151 (1994)).

Lipophilic solvents have been used in place of ethanol or propylene glycol which will not migrate to the shell and affect shell integrity and/or volatilize and thus impact on the concentration in the fill and on solubility. Triacetin has been used as a lipophilic cosolvent for cyclosporin microemulsion preconcentrates with a long chain triglyceride and high HLB surfactant (Hong (Chong Kun Dang Corp.) WO 99/000002). It has also been used alone and in a mixture with propylene glycol dicaprylate/dicaprate and a high HLB surfactant for ketoprofen and related anti-inflammatory acids (Shelley and Wei (Scherer) WO 95/31979A).

U.S. Pat. No. 5,993,858 discloses the use of an oil, high HLB surfactant, cosurfactant and triacetin as cosolvent for self-emulsifying formulations of hydrophobic drugs. Propylene carbonate has also been used as a lipophilic solvent for cyclosporin self-emulsifying systems (Woo (Novartis) WO 97/48410 and U.S. Pat. No. 5,958,876 (1999)). Use of ethyl lactate as a cosolvent for cyclosporin formulations, including clinical evaluation, has also been reported (WO 00/40219).

SUMMARY OF THE INVENTION

This invention provides pharmaceutical compositions that are liquid solutions, suspensions, and (oil-in-water) emulsions of CETP inhibitors, said solutions being orally administrable. The solutions or dispersions may be administered, for example, as fill in encapsulated dosage forms such as hard or soft gelatin capsules. The CETP inhibitors can be dissolved or dispersed in a variety of lipophilic vehicles, as further described and discussed below, such as digestible oils, solvents and surfactants, including mixtures of any two or more of the aforementioned vehicles.

Reference to a compositional component such as a “digestible oil”, to a “surfactant” and so forth, shall be understood as including mixtures of such components such as mixtures of digestible oils and surfactants.

In a first embodiment, the CETP inhibitor is dissolved or dispersed in a digestible oil such as a medium chain triglyceride oil or a mixture of digestible oils.

In a second embodiment, the CETP inhibitor is dissolved or dispersed in a digestible oil with one or more high HLB surfactants. The aforementioned solution or dispersion containing a high HLB surfactant or surfactant mixture may optionally contain one or more low HLB surfactants.

In a third embodiment, the CETP inhibitor is dissolved in a pharmaceutically acceptable lipophilic solvent optionally containing a digestible oil or digestible oil mixture. The CETP inhibitor solvent solution or dispersion or solvent/digestible oil solution or dispersion may optionally contain one or more high HLB surfactants and/or one or more low HLB surfactants.

The presence of one or more surfactants can, upon contacting the pharmaceutical composition with water, yield an emulsion that is either preformed by mixing with an aqueous phase or that is generated in vivo by contacting the aqueous fluids of the gastrointestinal tract. Formation of an emulsion can improve fasted bioavailability and thus reduce the food effect in man (i.e., the effect of food upon absorption and/or bioavailability of a drug). It can also allow the oil to be consumed as a beverage in addition to being administered in capsules. Use of surfactants to provide an emulsion can also be of value for increasing exposures in toxicology species. Combination of a digestible oil with a cosolvent can have the advantage of higher solubility and thus a higher dose in a given volume of formulation than is obtainable with the digestible oil alone. It is advantageous for bioavailability to have the entire dose dissolved. The presence of a third component in any of the above embodiments may also improve miscibility between the first two components.

Thus, in a first embodiment, the invention provides an orally administrable pharmaceutical composition comprising a CETP inhibitor and a lipophilic vehicle selected from a digestible oil, a lipophilic solvent (also referred to herein as a “cosolvent”, whether or not another solvent is in fact present), a lipophilic surfactant, and mixtures of any two or more thereof. Preferred embodiments include a CETP inhibitor and: (1) the combination of a pharmaceutically acceptable digestible oil and a surfactant; (2) the combination of a pharmaceutically acceptable digestible oil and a lipophilic solvent which is miscible therewith; and (3) the combination of a pharmaceutically acceptable digestible oil, a lipophilic solvent, and a surfactant.

In a particularly preferred embodiment, the invention provides a composition of matter for increasing the oral bioavailability of a CETP inhibitor. The composition comprises:

-   1. a CETP inhibitor; -   2. a cosolvent; -   3. a surfactant having an HLB of from 1 to not more than 8; -   4. a surfactant having an HLB of over 8 up to 20; and -   5. optionally, a digestible oil.

In such formulations, all of the excipients are pharmaceutically acceptable. The above composition is sometimes referred to herein as a “pre-concentrate”, in reference to its function of forming a stable emulsion when gently mixed with water or other aqueous medium, usually gastrointestinal fluids. It is also referred to herein as a “fill”, referring to its utility as a fill for a softgel capsule.

Reference herein is frequently made to a softgel as a preferred dosage form for use with this invention, “softgel” being an abbreviation for soft gelatin capsules. It is understood that when reference is made to the term “softgel” alone, it shall be understood that the invention applies equally to all types of gelatin and non-gelatin capsules, regardless of hardness, softness, and so forth.

A cosolvent means a solvent in which the CETP inhibitor of interest is highly soluble, having, for any given CETP inhibitor, a solubility of at least 150 mg/mL.

As noted above, and as discussed further below, a digestible oil can form a part of the pre-concentrate. If no other component of the pre-concentrate is capable of functioning as an emulsifiable oily phase, a digestible oil can be included as the oil which acts as a solvent for the CETP inhibitor and which disperses to form the (emulsifiable) oil droplet phase once the pre-concentrate has been added to water. Some surfactants can serve a dual function, however, i.e., that of acting as a surfactant and also as a solvent and an oily vehicle for forming an oil-in-water emulsion. In the event such a surfactant is employed, and, depending on the amount used, a digestible oil may be required in less of an amount, or not required at all.

The pre-concentrate can be self-emulsifying or self-microemulsifying.

The term “self-emulsifying” refers to a formulation which, when diluted by a factor of at least 100 by water or other aqueous medium and gently mixed, yields an opaque, stable oil/water emulsion with a mean droplet diameter less than about 5 microns, but greater than 100 nm, and which is generally polydisperse. Such an emulsion is stable for at least several (i.e., for at least 6) hours, meaning there is no visibly detectable phase separation and that there is no visibly detectable crystallization of CETP inhibitor.

The term “self-microemulsifying” refers to a pre-concentrate which, upon at least 100× dilution with an aqueous medium and gentle mixing, yields a non-opaque, stable oil/water emulsion with an average droplet size of about 1 micron or less, said average particle size preferably being less than 100 nm. The particle size is primarily unimodal. Most preferably the emulsion is transparent and has a unimodal particle size distribution with a mean diameter less than 50 nm as determined, for example, by dynamic light scattering. The microemulsion is thermodynamically stable and without any indication of crystallization of CETP inhibitor.

“Gentle mixing” as used above is understood in the art to refer to the formation of an emulsion by gentle hand (or machine) mixing, such as by repeated inversions on a standard laboratory mixing machine. High shear mixing is not required to form the emulsion. Such pre-concentrates generally emulsify nearly spontaneously when introduced into the human (or other animal) gastrointestinal tract.

The term “CETP inhibitor” implies any such compound that is sparingly or poorly water soluble. Generally, and as mentioned above, such compounds exhibit an aqueous solubility (e.g., in water) of less than about 10 μg/mL measured at about 22° C. and at a physiologically relevant pH of from 1 through 8.

Combinations of 2 surfactants, one being a low HLB surfactant with an HLB of 1 to 8, the other being a high HLB surfactant with a higher HLB of over 8 to 20, preferably 9 to 20, can be employed to create the right conditions for efficient emulsification. The HLB, an acronym for “hydrophobic-lipophilic balance”, is a rating scale which can range from 1-20 for non-ionic surfactants. The higher the HLB, the more hydrophilic the surfactant. Hydrophilic surfactants (HLB ca. 8-20), when used alone, provide fine emulsions which are, advantageously, more likely to empty uniformly from the stomach and provide a much higher surface area for absorption. Disadvantageously, however, limited miscibility of such high HLB surfactants with oils can limit their effectiveness, and thus a low HLB, lipophilic surfactant (HLB ca. 1-8) is also included. This combination of surfactants can also provide superior emulsification. A combination of a medium chain triglyceride (such as Miglyol® 812), Polysorbate 80 (HLB 15) and medium chain mono/diglycerides (Capmul® MCM, HLB=6) was found to be as efficient as Miglyol® 812 and a surfactant with an HLB of 10 (Labrafac® CM). N. H. Shah et al. Int. J. Pharm., vol 106, 15 (1994). The advantages of using combinations of high and low HLB surfactants for self-emulsifying systems, including promotion of lipolysis, have been demonstrated by Lacy, U.S. Pat. No. 6,096,338.

DETAILED DESCRIPTION

Suitable digestible oils, which can be used alone as the vehicle or in a vehicle which includes a digestible oil as part of a mixture, include medium chain triglycerides (MCT, C6-C12) and long chain triglycerides (LCT, C14-C20) and mixtures of mono-, di-, and triglycerides, or lipophilic derivatives of fatty acids such as esters with alkyl alcohols. Examples of preferred MCT's include fractionated coconut oils, such as Miglyol® 812 which is a 56% caprylic (C8) and 36% capric (C10) triglyceride, Miglyol® 810 (68% C8 and 28% C10), Neobee® M5, Captex® 300, Captex® 355, and Crodamol® GTCC. The Miglyols are supplied by Condea Vista Inc. (Huls), Neobee® by Stepan Europe, Voreppe, France, Captex® by Abitec Corp., and Crodamol® by Croda Corp. Examples of LCTs include vegetable oils such as soybean, safflower, corn, olive, cottonseed, arachis, sunflowerseed, palm, or rapeseed. Examples of fatty acid esters of alkyl alcohols include ethyl oleate and glyceryl monooleate. Of the digestible oils MCT's are preferred, and Miglyol® 812 is most preferred.

The vehicle may also be a pharmaceutically acceptable solvent, for use alone, or as a cosolvent in a mixture. Suitable solvents include any solvent that is used to increase solubility of the CETP inhibitor in the formulation in order to allow delivery of the desired dose per dosing unit. It is not generally possible to predict the solubility of CETP inhibitors in the individual solvents, but such can be easily determined by “trial runs”. Suitable solvents include triacetin (1,2,3-propanetriyl triacetate or glyceryl triacetate available from Eastman Chemical Corp.) or other polyol esters of fatty acids, trialkyl citrate esters, propylene carbonate, dimethylisosorbide, ethyl lactate, N-methyl pyrrolidones, transcutol, glycofurol, peppermint oil, 1,2-propylene glycol, ethanol, and polyethylene glycols. Preferred as solvents are triacetin, propylene carbonate (Huntsman Corp.), transcutol (Gattefosse), ethyl lactate (Purac, Lincolnshire, Nebr.) and dimethylisosorbide (sold under the registered trademark ARLASOLVE DMI, ICI Americas). A hydrophilic solvent is more likely to migrate to the capsule shell and soften the shell, and, if volatile, its concentration in the composition can be reduced, but with a potential negative impact on active component (CETP inhibitor) solubility. More preferred are the lipophilic solvents triacetin, ethyl lactate and propylene carbonate. Most preferred is triacetin.

Hydrophilic surfactants having an HLB of 8-20, preferably having an HLB greater than 10, are particularly effective at reducing emulsion droplet particle size. Suitable choices include nonionic surfactants such as polyoxyethylene 20 sorbitan monooleate, polysorbate 80, sold under the trademark TWEEN 80, available commercially from ICI; polyoxyethylene 20 sorbitan monolaurate (Polysorbate 20, TWEEN 20); polyethylene (40 or 60) hydrogenated castor oil (available under the registered trademarks CREMOPHOR® RH40 and RH60 from BASF); polyoxyethylene (35) castor oil (CREMOPHOR® EL); polyethylene (60) hydrogenated castor oil (Nikkol® HCO-60); alpha tocopheryl polyethylene glycol 1000 succinate (Vitamin E TPGS); glyceryl PEG 8 caprylate/caprate (available commercially under the registered trademark LABRASOL® from Gattefosse); PEG 32 glyceryl laurate (sold commercially under the registered trademark GELUCIRE® 44/14 by Gattefosse), polyoxyethylene fatty acid esters (availble commercially under the registered trademark MYRJ from ICI), polyoxyethylene fatty acid ethers (available commercially under the registered trademark BRIJ from ICI). Preferred are Polysorbate 80, CREMOPHOR® RH40 (BASF), and Vitamin E TPGS (Eastman). Most preferred are Polysorbate 80 and CREMOPHOR® RH40.

Lipophilic surfactants having an HLB of less than 8 are useful for achieving a balance of polarity to provide a stable emulsion, and have also been used to reverse the lipolysis inhibitory effect of hydrophilic surfactants. Suitable lipophilic surfactants include mono and diglycerides of capric and caprylic acid under the following registered trademarks: Capmul® MCM, MCM 8, and MCM 10, available commercially from Abitec; and Imwitor® 988, 742 or 308, available commercially from Condea Vista; polyoxyethylene 6 apricot kernel oil, available under the registered trademark Labrafil® M 1944 CS from Gattefosse; polyoxyethylene corn oil, available commercially as Labrafil® M 2125; propylene glycol monolaurate, available commercially as Lauroglycol from Gattefosse; propylene glycol dicaprylate/caprate available commercially as Captex® 200 from Abitec or Miglyol® 840 from Condea Vista, polyglyceryl oleate available commercially as Plurol oleique from Gattefosse, sorbitan esters of fatty acids (e.g. Span® 20, Crill® 1, Crill® 4, available commercially from ICI and Croda), and glyceryl monooleate (Maisine, Peceol). Preferred from this class are Capmul® MCM (Abitec Corp.) and Labrafil® M1944 CS (Gattefosse). Most preferred is Capmul® MCM.

In addition to the main liquid formulation ingredients previously noted, other stabilizing additives, as conventionally known in the art of softgel formulation, can be introduced to the fill as needed, usually in relatively small quantities, such as antioxidants (BHA, BHT, tocopherol, propyl gallate, etc.) and other preservatives such as benzyl alcohol or parabens.

The composition can be formulated as a fill encapsulated in a soft gelatin capsule, a hard gelatin capsule with an appropriate seal, a non-gelatin capsule such as a hydroxypropyl methylcellulose capsule or an oral liquid or emulsion by methods commonly employed in the art. The fill is prepared by mixing the excipients and CETP inhibitor with heating if required.

The ratio of CETP inhibitor, digestible oil, cosolvent, and surfactants depends upon the efficiency of emulsification and the solubility, and the solubility depends on the dose per capsule that is desired. A self-emulsifying formulation is generally useful if the primary goals are to deliver a high dose per softgel (at least 60 mg) with, generally, a much lower food effect than with an oil solution alone. In general, softgel preconcentrates having solubilities of CETP inhibitor of at least 140 mg/mL in the preconcentrate, and thus requiring higher amounts of cosolvent and lower levels of surfactants and oil, are preferred.

In general, the following ranges, in weight percent, of the components for a self-emulsifying formulation of CETP inhibitors are:

1-50% CETP inhibitor

5-60% cosolvent

5-75% high HLB surfactant

5-75% low HLB surfactant

Preferred ranges which have advantageously low food effects include those stated immediately below:

1-33% CETP inhibitor

0-30% digestible oil

15-55% cosolvent

5-40% high HLB surfactant

10-50% low HLB surfactant

More preferred ranges include

1-25% CETP inhibitor

10-25% digestible oil

20-35% cosolvent

10-30% high HLB surfactant

15-35% low HLB surfactant

If a specific goal is a minimal food effect, then a self-microemulsifying formulation is advantageous. Such formulations generally require relatively high levels of surfactants and a reduced amount of cosolvent. These formulations can, however, result in lower solubilities and, accordingly, a lower dose per capsule. These formulations have been found to increase fasted exposure.

General ranges, in weight percent, for the components for a self-microemulsifying formulation of CETP inhibitors are

1-40% CETP inhibitor

5-65% digestible oil

5-60% cosolvent

10-75% high HLB surfactant

5-75% low HLB surfactant

Preferred ranges include those which follow

1-20% CETP inhibitor

5-30% digestible oil

30-55%, high HLB surfactant

10-40%, low HLB surfactant

The invention is not limited by any particular structure or group of CETP inhibitors. Rather, the invention has general applicability to CETP inhibitors as a class, the class tending to be composed of compounds having low solubility. Compounds which may be the subject of the invention may be found in a number of patents and published applications, including DE 19741400 A1; DE 19741399 A1; WO 9914215 A1; WO 9914174; DE 19709125 A1; DE 19704244 A1; DE 19704243 A1; EP 818448 A1; WO 9804528 A2; DE 19627431 A1; DE 19627430 A1; DE 19627419 A1; EP 796846 A1; DE 19832159; DE 818197; DE 19741051; WO 9941237 A1; WO 9914204 A1; WO 9835937 A1; JP 11049743; WO 200018721; WO 200018723; WO 200018724; WO 200017164; WO 200017165; WO 200017166; EP 992496; and EP 987251, all of which are hereby incorporated by reference in their entirety.

Oral delivery of many CETP inhibitors is particularly difficult because their aqueous solubility is usually extremely low, typically being less than 2 μg/ml, often being less than 0.1 μg/ml. Such low solubilities are a direct consequence of the particular structural characteristics of species that bind to CETP and thus act as CETP inhibitors. This low solubility is primarily due to the hydrophobic nature of CETP inhibitors. Log P, defined as the base 10 logarithm of the ratio of the drug concentration in octanol to the drug concentration in water in a partitioning experiment, is a widely accepted measure of hydrophobicity. In general, Log P values for CETP inhibitors are greater than 4 and are often greater than 5 to 7. This property may also be calculated from the structure of the molecule and is designated “cLog P.”. The calculation of cLog P values from chemical structures is given in Leo, A. J.; “Calculating log P from structures”, Chem. Rev. 1993, 93, 1281. Thus, the hydrophobic and insoluble nature of CETP inhibitors as a class pose a particular challenge for oral delivery. Achieving therapeutic drug levels in the blood by oral dosing of practical quantities of drug generally requires a large enhancement in drug concentrations in the gastrointestinal fluid and a resulting large enhancement in bioavailability.

The formulations of this invention will be administered in such an amount that an effective dose of the CETP inhibitor of interest is administered to the patient. The amount of CETP inhibitor will generally be known or determined by the attending physician. Thus the amount or volume of preconcentrate administered will be determined by the amount of CETP inhibitor prescribed and/or otherwise desired as a dose and the solubility of the CETP in the preconcentrate. In general, an effective dose for most CETP inhibitors is in the range of from 5 to 500 mg, preferably 10-300 mg, more preferablly 10-200 mg per day, in single or divided doses. The compositions of the invention are pre-concentrates for emulsification which are generally administered orally, in soft or hard gelatin capsules, gelatin encapsulation technology being well known to the pharmaceutical arts. Such pre-concentrates can also be administered in aqueous oral emulsions by adding the pre-concentrate to water or other aqueous liquid (e.g., soda). They can be mixed with an aqueous liquid and sold as pre-formed emulsions, or added to food such as ice cream.

EXAMPLE 1

This Example (and Examples 2 through 5) illustrates making a composition according to the invention and using it to make softgel capsules containing it.

Capmul® MCM was heated to 55° C. and mixed. To a 2 liter glass beaker was added 277 gm of Miglyol® 812, 510 gm of triacetin, 318 gm of Polysorbate 80, and 442 gm of Capmul® MCM. After stirring for one hour, this solution was added to 161 gm Compound A and the resulting mixture stirred at ambient temperature for 8 hours with scraping of walls as needed.

EXAMPLE 9

This example describes the determination of solubility of CETP inhibitors in excipients and emulsion preconcentrates and also an initial assessment of emulsion quality (Table 9a-9d).

The solubility of CETP inhibitors in excipients and in formulations was determined by adding an excess of compound to the medium in question. The mixture was agitated by rotation over a period of days at ambient temperature until the concentration in solution had reached an equilibrium as judged by similar measurements for consecutive time points. Concentrations were measured by filtration of aliquots with a PTFE syringe filter and assay by HPLC as described in Example 11.

For CETP inhibitors where quantities were limited, an estimate of solubility was obtained by addition of vehicle to a known quantity of the compound and mixing in an ultrasonicator bath for 90 minutes, followed by overnight equilibration at ambient temperature. Addition of vehicle was repeated until a solution was achieved.

The extent of emulsification was determined by mixing the preconcentrate and water in a ratio of 1:100 and 1:10 by gentle inversion (5×), visual inspection, and examination under an optical microscope, using a polarizing filter to check for the appearance of crystals. Droplet size determined by this approach is expressed as the upper limit for the average droplet size, since submicron droplets cannot be detected by this method.

The results in. Table 9a show that the solubility of Compound A in Miglyol® 812 is only sufficient for a 50 mgA/mL fill (30 mgA in a 0.6 mL softgel), while cosolvents such as triacetin and propylene carbonate provide ca. 4× higher solubility and those such as ethyl lactate and dimethyl isosorbide nearly double those levels. Solubility and emulsification data for preconcentrate solutions of Compound A is shown in Table 9c. Use of propylene carbonate and triacetin as cosolvents allow solubilities suffcient in some cases for a 100 mgA/mL self-emulsifying fill. (e.g., Formulations M, O, Q, and R, see Table 9c)

Higher levels of surfactants are often required to yield self-microemulsifying formulations and in these cases solubilities only permit in general a 50 mgA/mL fill using triacetin as the cosolvent (e.g. Formulation EE, Y, and PP). Use of propylene carbonate or ethyl lactate as cosolvent can permit a 100 mgA/mL fill (e.g., Formulations A, B, XX, YY, and ZZ) that has sufficient surfactant to yield microemulsions. However, triacetin has the advantage of good precedence in oral dosage forms (and has GRAS status). Dynamic light scattering was utilized to further characterize the sub-micron particle size distribution for microemulsions as described in Example 10.

The solubility in ethyl lactate permits a self-emulsifying 150 mgA/mL fill to be prepared (e.g Formulation WW). However, the solubilities of emulsion preconcentrates shown in Table 9a and 9c cannot reliably be predicted based on the solubilities of the components alone. This is exemplified by formulation WW (Table 9c), which exhibits considerably greater solubility than the corresponding formulation using dimethyl isosorbide (Formulation AAA), although the opposite would have been predicted based on solubilities in the individual cosolvents. Also, lack of data for excipients that are solids at room temperature also hinders prediction.

All of the emulsions prepared from these formulations exhibited good physical stability, i.e. there was no sign of crystallization or change in particle size based on microscopic examination after standing overnight at ambient temperature.

Results obtained for other CETP inhibitors are shown in Tables 9b and 9d. In case of Compound D (Table 9b), the average emulsion particle size is <5 microns.

EXAMPLE 10

Preliminary particle size analysis data has been obtained on selected formulations using a dynamic light scattering particle size analyzer (ZetaPals, Brookhaven Instruments, Inc.) for measurement of sub-micron particle distribution. The formulation solutions were diluted 1:100 in HPLC-grade water (previously filtered through a 0.22 μm syringe filter). The resulting mixture was gently inverted five times to create the emulsion. Each emulsion sample was then analyzed at a temperature of 37° C. Triplicate measurements were made at each time point (0, 30 min).

The results shown in Table 10 confirm that formulations O, Q and R are self-emulsifying formulations with a mean particle size above 100 nm. Formulations such as A and B have mean particle sizes in the microemulsion range but with significant populations of larger particles and are slightly turbid. Formulation EE is very slightly turbid with a trace of larger particles. Use of Cremophor® RH 40 as the high HLB surfactant yielded formulations Y, PP, XX, and ZZ that form transparent microemulsions with all particles smaller than ca. 100 nm, as is the case for Neoral®. Only formulation Y showed a stable unimodal distribution that did not change, even with stirring.

EXAMPLE 11

The fills prepared in the above examples were hand-filled into hydrophobic softgel shells and heat sealed, and then placed on stability under accelerated conditions in sealed HPDE bottles with child-resistant caps. The fills were assayed at intervals by dilution of aliquots into acetonitrile and gradient HPLC analysis on a Water Symmetry C-8 column (3.9×150 mm, 5 micron) at 30° C. at a flow rate of 1 mL/min. The mobile phase program was a 25 minute gradient from 100% A to 50% A/50% B (A=400/300/300/0.8 v/v Di H₂O/Acetonitrile/2-Propanol/Phosphoric Acid and B=2-Propanol), followed by a 5 minute hold at this condition and a 10 minute gradient to the initial condition. The detection method was UV absorbance at 210 nm.

There was no impurity formed at ≧0.1% peak area vs. parent for any formulation in Table 11. There was no sign of crystallization in the fill under any condition based on microscopic examination. There was also no indication of seal leakage.

Disintegration times in water at 37° C. were less than 15 min for Formulations A, B, and O after storage under accelerated conditions for 6 weeks.

Formulation O softgels of Compound A manufactured by machine have been shown to be stable for 9 months under accelerated conditions. Formulation M softgels of Compound D have been shown to be stable for 6 months under accelerated conditions.

EXAMPLE 12

Fills were prepared as described in above examples and then encapsulated in #00 hard gelatin capsules. Male Beagle dogs (n=6) between the ages of 2-5 and weighing 6-12 kg were dosed with capsules followed by 50 mL of water. Dogs were also dosed with 30 mgA Miglyol® 812 softgels and aqueous, crystalline drug suspension. The dogs were either fasted or fed just prior to dosing with 14 g of dry dog food and 8 gm olive oil. The same set of dogs were used for all formulations, except where indicated. Blood samples were obtained from the jugular vein of each dog at 0, 0.5, 1,2, 3,4, 6, 8 and 12 hr and analyzed by acidifying the plasma, solid phase extraction, and analysis by LC/MS/MS with a lower limit of quantitation of 25 ng/mL.

The results, in Table 12a and 12b are shown in terms of Area Under the Curve (AUC), Cmax, the maximum concentration of drug measured in the plasma, and Tmax, the time in hours it took to reach Cmax. Unless otherwise indicated, results are for the fasted state. Miglyol® softgels have a very low fasted exposure and thus a high food effect. The fasted exposure is higher than that for crystalline suspension, while the fed exposure using this high oil meal is the same. Thus Miglyol softgels provide a lower food effect than crystalline drug. At the same dose of 90 mgA, formulations such as A, O, and C that include surfactants and cosolvent have much higher fasted exposures and only a ca. 3× food effect. The fed exposures are also higher than for Miglyol® 812 softgels and crystalline drug. Poorer fasted exposure was obtained for Formulation WW, which contains a high level of ethyl lactate as a cosolvent.

The transparent self-microemulsifying formulations EE and PP at a dose of 30 mgA have a food effect of only 2.2-2.4. For the stable, monodisperse microemulsion Y there is a much higher fasted exposure at 30 mgA than for the self-emulsifying formulation O. The fasted exposure for Y was the same as the fed, i.e. there was no food effect.

EXAMPLE 13

This example further illustrates the determination of equilibrium solubilities of CETP inhibitors in vehicles. For experimental methods, see Example 9.

The solubility of crystalline CETP inhibitors in representative vehicles was determined by adding an excess of compound to the vehicle in question. The mixture was agitated by rotation over a period of days at ambient temperature until the concentration in solution had reached equilibrium as judged by similar measurements for consecutive time points. Concentrations were measured by filtration of aliquots with a PTFE syringe filter and assayed by HPLC.

The concentrations of CETP inhibitor in each vehicle were assayed at intervals by dilution of aliquots into acetonitrile and gradient HPLC analysis on a Water Symmetry C-8 column (3.9×150 mm, 5 micron) at 30° C. at a flow rate of 1 mL/min. The mobile phase program was a 25 minute gradient from 100% A to 50% A/50% B (A=400/300/300/0.8 v/v DI H₂O/Acetonitrile/2-Propanol/Phosphoric Acid and B=2-Propanol), followed by a 5 minute hold at this condition and a 10 minute gradient to the initial condition. The detection method was UV absorbance at 210 nm.

The results of the equilibrium solubility studies are given in Tables 13a-13c.

EXAMPLE 14

For CETP inhibitors where quantities were limited or the samples were amorphous solids, an estimate of solubility was obtained by addition of vehicle to a known quantity of the compound and mixing in an ultrasonicator bath for 90 minutes, followed by overnight equilibration at ambient temperature. Addition of vehicle was repeated until a solution was achieved. From the total volume of vehicle added to solubilize the CETP inhibitor compound, the solubility value, or so-called microsolubility, was calculated by the equation: Weight of sample (mgA)/vehicle volume (mL)=Microsolubility (mgA/mL)

The microsolubility values for CETP inhibitors in various vehicles are given in Tables 14a-14c.

EXAMPLE 20

Chemical and physical stability for the formulation of Example 8 was determined for 30 mgA Miglyol® (#11 oblong) softgels stored in white HPDE bottles (child-resistant closures). After storage at 40° C./75% RH for 6 months there was no change in potency and no degradation was detected (peak area <0.05% relative to parent) as determined by HPLC analysis of the entire softgel. The appearance (color, shape, seal integrity) was unchanged, and disintegration occurred within 15 minutes in water (USP<701>). Softgels stored at 5° C. and 25° C./60% RH were stable for 18 months.

EXAMPLE 21

Either oils or preformed emulsions of Compound A were administered to Sprague Dawley rats by oral gavage and the results are shown in Table 21a. Emulsions were prepared as indicated in Examples 17-19. Emulsions prepared from olive oil/surfactant provided the best results. The solubility and thus the accessible dose could be increased by using cosolvents (e.g. caprylic acid and/or triacetin) or using a triglyceride with improved solubility (Miglyol® 812), but this did not provide any improvement in exposure over much lower doses in olive oil/Cremophor® EL. Administration of pre-formed emulsions gave superior results to the oil, especially at higher dose volumes where mixing of phases in vivo may be less efficient.

In contrast to the results in rats, emulsions in Miglyol® 812/Cremophor® EL yielded far superior results to olive oil/Cremophor® EL in cynomologous monkeys (Table 21b), and much better results than for Miglyol® alone. Use of an emulsion prepared from crystalline (ethanolate) drug allowed comparible exposures to be achieved to those for more soluble amorphous drug in Miglyol® alone. Excellent dose proportionality was also obtained.

The need for the presence of a high concentration of the long chain triglyceride olive oil for efficient absorption in the rat, but not the monkey, suggests that the lymphatic pathway plays a more important role for absorption of this drug in rats. An important role for lymphatic absorption for Compound A is consistent with its very high lipophilicity.
